WILLIAM ROCKWELL CLOUG-H, OF ALTON, NEW HAMPSHIRE.

POCKET IMPLEMENT.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed June 28, 1918. Serial No. 242,342.

To all whom it may concern:

Be it known that I, WILLIAM ROCKWELL CLOUGH, a citizen of the UnitedStates, and a resident of Alton, in the county of Belknap and State ofNew Hampshire, have invented certain new and useful Improvements inPocket Implements, of which the following is a specification.

The invention pertains more particularly to pocket implements of thecharacter known and classed as pocket vknives and comprising a handleand suitable tools pivoted between the sides thereof and to foldtherein, these tools sometimes consisting of cork screws having a wormportion and an integral tang, as heretofore made. There has not beenmuch difficulty connected with the manufacture of pocket-knife handles,but considerable expense has been involved in the manufacture of thecork-screws intended to be pivotally secured between the opposite sidesof said handles.

Thepurpose of my invention is to materially simplify and lessen the costof manufacture of cork-screws for handles of the pocket knife type, andin carrying out my invention I form the worm of the screw and the tangtherefor in separate pieces capable of being properly assembled andapplied tothe handle. The tang will usually be of a different characterof metal from that of the body of the worm of the corkscrew, and it willbe formed from a block or blank of untempered stock, and the tangblankwill have a socket therein to receive the shank-end of the worm, andfinally I will preferably secure said shank-end in said socket bydriving portions of the blank between integral portions thereof, afterwhich the blank will be finished off to con, stitutea tang of therequisite shape and dimensions. The material of the tang blank may bereadily hammered, ground and drilled, and in addition may be of a metalwhich would insure smoother or' easier opening' and closing movements ofthe cork-screw than is customary in instances in which the body and tangof the cork-screw are in one piece of tempered or hardened steel and inwhich the hardened tang is to move against the inner side surfaces ofthe parts of the handle.

The advantages of my invention may be readily appreciated in consideringits use in the manufacture of cork-screws for pocket knife handles.These cork screws have heretofore been of forged metal, and the body andtang thereof have been in one piece and in the customary and regularmanufacture these cork-screws have added materially to the expense ofthe pocketknife, which expense vmy invention materially'lessens and atthe same time improves the character of the cork-screw for practicalpurposes.

In accordance with my invention I form the body or worm of thecork-screw from arod of wire, spirally coiled, and the tang thereof is aseparate piece in which the shank end of said body is secured, said tangbeing formed from a blank and adapted for correct application to ahandle of the'pocket knife type. It will appear obvious that the corkscrew of my invention is simpler and -less*expensive than the one pieceforged metal cork-screws that have heretofore been universally employedin pocket knives.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the ac companyingdrawings, in which:

Figure 1 is a side elevation, partly broken away, of a pocketrknifehaving its corkwith andjembodying the invention, said member beingillustrated as opened outwardly from said handle;

.screw member constructed in accordance Fig. 2 is a side elevation,partly broken away and partly in section and on an enlarged scale, ofthe cork-screw worm and blank for the tang thereof illustrated in theirpreliminary associated relation;

Fig. 3 is a transverse section through the same, taken on the dottedline 3-3 of Fig. 2;

Fig. 4 is a corresponding section of the same illustrating thetang-blank having had its opposite sides driven inwardly betweenportions of the shank of the worm for fasand 18 being presented asillustrative of the various implements commonly employed in connectionwith pocket-knife handles.

The blade 16, cork-screw 17 and gimlet 18 are shown in Fig. 1 as'securedto finished tangs numbered, respectively, 19, 20 and 21, and these tangsare secured to the handle 15 by means of customary pins numbered,respectively, 22 and 23.

Figs. 2 to 5 inclusive illustrate the method of carrying my inventioninto effect, as applied to the cork-screw 17 and tang 20 thereof. Thebody of the corkscrew 17, in accordance with my invention and which isone of the advantages thereof, is formed from a rod of wire spirallycoiled to form the worm in the customary manner, and the tang 20 isformed from a separate blank, block or piece of metal numbered 24 inFigs. 2 to 5 inclusive. The blank 24 is of suitable dimensions to beshaped into the tang 20, which in finished outline may correspond withthe cork-screw tangs to be found at present in pocket-knives and whichare integral with specially forged and wrought worms.

The blank 24 is preferably of rectangular outline and of suitablelength, width and thickness, and at one end the blank 24 is formed witha socket 25 to receive the folded-over end 26 of the shank of thecorkscrew 17, and which end has its members 27, 28, except where theymerge into each other, spaced apart, the member 28 setting off at anangle to the member 27 and an approximately inverted V-space 29 beingleft between said members. The end 26 of the cork-screw shank isinserted within and, by preference, tightly binds againstthe walls ofthe socket 25 in the blank 24, this feature of the construction, asidefrom other advantages, serving to properly aline the corkscrew andblank; and after said end 26 is properly seated within the socket 25, Idrive one or both sides of the blank 24, at the location of the V-space29, inwardly against and between the members 27, 28 of said end 7 26, sothat the blank becomes transformed from its initial condition shown inFig. 3 to that illustrated in Fig 4, in which I indicate that both sidesof the blank have been driven or pressed inwardly against and betweenthe members 27, 28. The pressing inwardly of the sides of the blank 24against and between the members or portions 27, 28 of the shank of thecork-screw has the effect of rigidly connecting said blank and corkscrewin a very eflicient manner and without any further securing means beingrequired. The driving inwardly of the sides of the blank 24 results in adisplacement of portions of the metal of the blank and this creates insaid sides the grooves or indentations 30, which I remove by grindingdownthe faces of said sides until said indentations disappear, leavingthe blank with smooth opposite faces, as I represent in FVhen the stageof manufacture indicated in Fig. 5 has been reached, the cork-screw andtang-blank securely connected there with will be subjectedto suchfurther treatment as said blank may require to shape and proportion itfor the handle 15 and back-spring 31 therein.

In carrying out my invention I may depress one or both sides of theblank 24 against and between the portions 27, 28 of the shank of thecork-screw but preferably both of said sides will be so depressed, as Iillustrate, in order to secure a highly efficient connection of thetang-blank and worm. p p

The portion 28 of the shank end 26 of the cork-screw will be placed atthat edge of the blank 24 which in the finished tang will be at theinner edge thereof when the the cork-screw isturned into the handle 15,so that the body of the worm will be eccentric to the pivot-pin 23 andlie exposed within the side-recess 32 of the handle 15, as will beunderstood on reference to Figs. 1 and 2. p

'In accordance with my invention the worm of the cork-screw may beformed of spirally coiled wire, such as has been found effective in thepractical manufacture of 7 cork-screws, as distinguished from corkscrewsmade from metal wrought and public. In addition, the' cork-screwconstructed in accordance with my invention is more eflicient than thecork-screw heretofore placed in pocket-knives madeof forged metal.

What I claim as m invention and desire to secure by Lettersatent, is:

1. A handle comprising opposite sides and a back spring, having, incombination, a tang cooperating with said spring and pivotally securedbetween said sides, and a spirally coiled wire cork-screw having a" Thepresence of the" worm and shank in one integral piece, said shank havingat its outer en a folded over portion or return bend, and said tanghaving a socket holding said outer end of said shank and also having aportion of its metal interposed between portions of the members of saidreturn bend.

2. A handle comprising opposite sides and a back spring, having, incombination, a tang cooperating with said spring and pivotally securedbetween said sides, and a spirally coiled wire cork-screw having a wormand shank in one integral piece, said shank having at its outer end afolded over portion or return bend, and said tang having a socketholding said outer end of said shank and also having a portion of itsmetal interposed between portions of the members of said return bend,and the pivot for said tang being set off from the central longitudinalplane of the body of said Worm.

3. A handle comprising opposite sides and a back spring, having, incombination, a tang cooperating with said spring and pivotally securedbetween said sides, and a spirally coiled wire cork-screw having a wormand shank in one integral piece, said shank having at its outer end aspace between contiguous portions thereof, and said tang having a socketholding said outer end of said shank and also having a portion of itsmetal interposed into said space.
